FRANCIS M. FRANKLIN, OF SPRINGFIELD, OHIO, ASSIGNOR TIO HIM'- SELF ANDEDWARD M. DOTY, OF SAME PLACE.

Letters Patent No. 91,109, dated June 8, 1869; antedated May 24, 1869.

IMPROVEMENT 1N FLOWS.

The Schedule referre to in these Letters Patent and making part of thesame.

To all whom tt may concer/n:

' Be it known that I, FRANCIS M. FRANKLIN, of Springfield, in the countyof Clarke, and in the State of Ohio, have invented certain new anduseful Improvements inPlows; auddo hereby declare that the following isa full, clear,'and exact description thereof', reference beinghad to theaccompanying drawings,

The'nature of my invention consists in the construction of' the sheathto a plow, and in the ma'nner'of attaching lthe plow-beam to the handle.

In order` to enable others skilled in the art to which my inventionappertaius, to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, whichform a part of this specification, and in which- Figure l is a sideview, and Figure 2, a front view.

A represents the plow-beam, B, the handle, and C, the sheath, to'whichthe plow D is secured, said plow The sheath' C is of the usual lengthand size, of round wrought-iron, vertical, with a forward curvature.

At the height of about eleven inches it bends out from the line ofthebeam; then, at the additional height of about five inches, it has aright angle, bent across the line of the beam. This horizontal part ofthe ysheath.I term a knee; it is about four inches long. 4The beam restson about three inches of the knee, and the projecting inch is flat, andhas a hole through it,

The front of the dra ght-rod F has aneye, for a ring, G, and back ofsaid1 eye, for a suitable distance, the draught-rod is dat, and securedto the the beam A by one or more screw-bolts.

The rear end passes through an eye in a bolt, H, which passes up throughthe beam just in front ofthe knee on the sheath C.

The draught-rod F has a bend just back of `said knee, and passes upthrough thebeam. Ihus the rod F and bolt H, each having a washer andnut, form a stirrup, to keep the beam rm to the knee.

By this arrangement the draught-rod becomes a support to the beam in agreater degree than can be obtained by any former model of attachment,thus gaining the advantage at this point of adding the. power of tensionto the strength of the beam, through the medium ofthe angle.

point of l level of the knee, an upright, I, is attached by screw- Uponthe handle B, at a proper distance below the bolts.

The lower end of the upright, I, is flat, and the bolts pass throughholes in that part, to secure it to the handle. Just above the flatpart, the upright angles, incline alittle forward; A screw is cut ontheupright, to the height of about five inches.

A nut, a, is ruu down to 4the flat, and the upright passes up through ahole asuitabIe distancev from the rear end of the beam.l The directionof this hole, and the position of the upright should be decided by atram pivotedon the centre ofthe knee;

The uprivht, I, projects above the beam, to receive a washer an( nut, b.

Above the nut b the upright is reduced in thickness, and passes throughthe end of a forked brace, J, and has a nut, c, above said brace.

The forks of the brace J extend back, one passing on each side of thebeam-handle B, and have holes in their rear ends, through which anirouround, L, passes, Y' going also through both handles, and through twothimbles, d d. i

rlhe thim'bles dd are bell-shaped, and place-dhctween the handles andthe ends ofthe brace, the large ends against the handles, and thesmaller, outer ends, against the brace. The thimble and brace betweenthe handles are pressed against the handle by a iirrn washer, e, ou therouudL; those outside are kept to s the handle by a nut, f, on the endof the round.

It will be seen, that by.raisng or lowering the rear end of the beam A,on the upright, I, by means of the nuts a and b, the heightof the plowis easily regulated.

`Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is-`v if 1. The bent sheath C, constructed and lused substantially as and forthe purposes as herein set fort-lnV 2. The arrangement of the beam A,sheath C, bent draught-rod F, eye-bolt H, upright, I, and handle B,

all substantially as shown and described.

3. Ihe arrangement of the handle B, -upright, I, round, L, forked braceJ, thiuibles d d, washers e c, and nuts c and f j, all substantially asherein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand,this 30th day of May, 1868.

. FRANCIS M. FRANKLIN.
